Go to the site in http:#a35129408. Bullet IT Professional. Check the OSes you need to manipulate. You should be able to download the require patches for distribution.

Alternately, you should be able to use WSUS (if you can get it working on your already troubled SBS server) or if you don't use WSUS, get each client OS to do a Windows Update and get the required patch.
